Aluminum-copper-silicon calibrated metal pipe Yekyas

This product is made of calibrated aluminum base metal containing 26% by weight of copper and 8% by weight of silicon by horizontal centrifugal casting method. In the inner layer, the hardness is 153 Vickers, and the wear rate is 40.5 g / m2, which decreases to 149 Vickers and increases to 0.7 g / m2 by reaching the outer layer, respectively. Also, in the middle layer, the compressive strength is 460 MPa.

By changing the production conditions of the calibrated pipe of the same material, in the inner layer, the hardness is 380 Vickers, and the wear rate is 0.04 g / m2, which is reduced to 100 Vickers and to 3.3 g, respectively, until it reaches the outer layer. Per square meter increases. Also, in layers, the minimum compressive strength is 100 MPa. In this product, as shown in the figure below, the targeted distribution of phases (in light color) is clearly visible.
